UP 4014 Nov 1941 69585 (69572, September 1941)

General Notes:

a. UP 4014 was retired in June 1961 and donated to The Railway & Locomotive Historical Society, Southern California Chapter, for display at the Los Angeles County Fairgrounds in Pomona, California; moved to Pomona in January 1962, arriving on January 6th. (photo showing UP 4014 on AT&SF at Cajon in Trains magazine, April 1962, page 10)
b. UP 4014 currently carries builder plates reproduced from an original plate from UP 4001, with builder number 69572 and builder date September 1941. The original left side builder plate on 4014 was stolen the first night after it arrived in Pomona in January 1962. The right side plate was cracked with a missing corner piece. After a few years, a local R&LHS member offered his original plate from UP 4001 to serve as an original to have reproduction copies made, and it is these reproduction copies that are currently mounted on UP 4014.
c. On July 23, 2013, the R&LHS Southern California Chapter and Union Pacific Railroad announced an agreement for return of Big Boy steam locomotive no. 4014 to Union Pacific. Union Pacific intends to restore and operate no. 4014 as part of its Heritage Locomotive fleet. The restoration will likely take until 2018 to complete.
d. On November 14, 2013, after preparation of the locomotive and the site itself, the process began to move the locomotive from its display site, across the large adjacent parking lot for approximately 5,000 feet by the use of temporary panel track sections. The move continued until November 26th when the locomotive, still on temporary track, was sitting at the far north end of the parking lot, adjacent to the tracks of MetroLink.
e. On January 21, 2014, to avoid confusion with UP's SD70M no. 4014 (built in 2001), UP steam 4-8-8-4 no. 4014 was renumbered in UP's computer system to UPP 4014; shown as having 2000 hp and a 6000-gallon fuel tank.
f. On January 25 and 26, 2014, UP 4014 was moved from the Los Angeles County Fairgrounds "Fairplex" to UP's West Colton yard. Preparation for the move began when the tracks of Metrolink were cut and moved to connect with adjacent temporary track that UP 4014 was sitting on. The connection was made at about midnight and UP 4014 was pulled onto the connection at about 2:50 a.m. by UP 1996, the SD70ACe SP Heritage unit. The special train was moved to Covina Metrolink station, arriving at about 4:30 a.m. Held for public display until about 8:00 a.m. The move was completed when the special train arrived at West Colton at about 2:30 p.m. UP 4014 was to remain at West Colton until late April 2014.
g.

On January 26, 2014, after UP 4014 was moved from the fairgrounds at about 5:00 a.m., UP moved a donated SD40-2 (UP 3105), a boxcar (UP 453665) and a caboose (UP 24567) to the display site to replace UP 4014 as part of the railroad display at the Rail Giants museum; equipment was held outside the Fairplex grounds until February 15 due to car racing event; equipment was brought into the Fairplex using temporary panel track and moved using UP 3105 as motive power, across the parking lot along the same route used to remove UP 4014; the movement was completed on Saturday February 22 when the donated equipment was placed on panel track owned by the Rail Giants museum.

Equipment donated to Rail Giants to replace UP 4014:

  • UP 3105 EMD SD40-2, built as MP 6027 in June 1979; to UP by merger in 1982; renumbered to UP 3927 in January 1987; renumbered to UP 3105 in January 2003.
  • UP 453665, insulated boxcar Class BI-70-14, built January 1974.
  • UP 24567 Caboose, built as CRI&P 17149 in November 1967; to UP 24567 in April 1980; assigned to UP's steam program.
h. The move of UP 4014 from West Colton, California, to Cheyenne, Wyoming, began on April 28, 2014, with arrival at Cheyenne completed on May 8, 2014.
